Meta is pushing back against a ban on WhatsApp from government devices.

The chief administrative officer, or CAO, of the U.S. House of Representatives told staffers on Monday that they are not allowed to use Meta’s popular messaging app. The CAO cited a lack of transparency about WhatsApp’s data privacy and security practices as the reason for the ban, according to a report by Axios that cited an internal email from the government office.

The CAO told House staff members in the email that they are not allowed to download WhatsApp on their government devices or access the app on their smartphones or desktop computers, the report said. Staff members must remove WhatsApp from their devices if they have the app installed on their devices, the report said.

“Protecting the People’s House is our topmost priority, and we are always monitoring and analyzing for potential cybersecurity risks that could endanger the data of House Members and staff,” U.S. House Chief Administrative Officer Catherine Szpindor told CNBC in a written statement.

Meta spokesperson Andy Stone on Monday responded to the report via a post on X, saying the company disagrees “with the House Chief Administrative Officer’s characterization in the strongest possible terms.”

“We know members and their staffs regularly use WhatsApp and we look forward to ensuring members of the House can join their Senate counterparts in doing so officially,” Stone said.

In a separate X post, Stone said WhatsApp’s encrypted nature provides a “higher level of security than most of the apps on the CAO’s approved list that do not offer that protection.”

Some of the messaging apps the CAO said are acceptable alternatives to WhatsApp include Microsoft Teams, Signal and Apple’s iMessage, the Axios report said.

Meta is currently embroiled in an antitrust case with the Federal Trade Commission over the social media company’s acquisitions of WhatsApp and Instagram.

Last week, Meta debuted ads in WhatsApp in an effort to monetize the app that CEO Mark Zuckerberg has deemed “the next chapter” for his company’s history.

Amazon‘s second batch of Kuiper internet satellites reached low Earth orbit on Monday, adding to its plans for a massive constellation and ramping up competition with SpaceX’s Starlink.

A United Launch Alliance rocket carrying 27 Kuiper satellites lifted off from a launchpad at the Cape Canaveral Space Force Station in Florida at 6:54 a.m. ET, according to a livestream.

“We have ignition and lift off of United Launch Alliance Atlas V rocket carrying satellites for Amazon’s Project Kuiper internet constellation, continuing a new chapter in low Earth orbit satellite connectivity,” Ben Chilton, an ordnance engineer at ULA, said on the livestream following the launch.

Monday’s mission was rescheduled twice, owing to inclement weather and a problem with the rocket booster.

Six years ago, Amazon unveiled its plans to build a constellation of internet-beaming satellites in low Earth orbit, called Project Kuiper. The service will compete directly with Elon Musk’s Starlink, which currently dominates the market and has 8,000 satellites in orbit.

Amazon in April successfully sent up 27 Kuiper internet satellites into low Earth orbit, a region of space that’s within 1,200 miles of the Earth’s surface.

The 54 craft currently in orbit are the start of Amazon’s planned constellation of 3,236 satellites. The company has to meet a Federal Communications Commission deadline to launch half of its total constellation, or 1,618 satellites, by July 2026.

The company has booked more than 80 launches with several providers, including rival SpaceX, to deliver Kuiper its satellites into orbit.

Tesla‘s driverless robotaxi finally hit the road this weekend, sending shares of the electric vehicle maker up 10% on Monday.

The EV giant debuted autonomous rides in Austin, Texas, on Sunday, opening the service to a limited number of riders by invitation only. CEO Elon Musk said in a post on social media platform X that customers were charged a flat fee of $4.20.

“Super congratulations to the @Tesla_AI software & chip design teams on a successful @Robotaxi launch!! Culmination of a decade of hard work. Both the AI chip and software teams were built from scratch within Tesla,” he said in a post.

One tester wrote on X that they did 11 with the service with “zero issues.” Musk reposted numerous firsthand encounters with the services.

Musk has long promised a driverless Tesla robotaxi fleet to investors, amping up the pressure to deliver.

The launch puts Tesla head-to-head with Alphabet‘s Waymo, which is already operating a fleet of robotaxis in several cities across the U.S. and reached 10 million trips last month.

Musk told CNBC’s David Faber last month that Tesla aims to have “Hundreds of thousands, if not over a million” self-driving cars in the U.S. by the end of next year. In May, Musk first announced plans to launch the service in Austin, with later debuts set for Los Angeles and San Francisco.

Heading into the launch, Tesla faced pushback from a group of Democratic lawmakers in Texas and public safety activists urged the company to delay the debut.

Tesla’s full-self driving capabilities, which feature a standard FSD or FSD supervised, include automatic steering and parking, but have been linked to accidents and fatalities, according to data tracked by the National Highway Traffic Safety Administration.
